Virtual Prop Control via Periodic Adhesion Box Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile shooting games, the small screen size makes it difficult for players to conveniently operate virtual shooting props, leading to inefficiencies in selecting targets with existing adhesion functions, as current methods lack effective detection of adhesion boxes without unnecessary computation.
Innovation Solution
A virtual prop control method and apparatus that displays a crosshair and detects an aiming ray's contact with adhesion boxes of non-target virtual operation objects only in response to input operations, determining the adhesion target by projecting positions onto a plane and calculating distances to select the closest target, thereby reducing computation and improving hit rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous detection of adhesion boxes is performed to improve target selection accuracy, then measurement precision is improved, but use of energy and computation increase
Solution Approach 1:
The patent implements periodic detection by triggering adhesion box detection only at specific moments (when weapons are equipped, during shooting actions, or when targets enter detection ranges) rather than continuously. This periodic action maintains target selection accuracy when needed while significantly reducing computation energy consumption during non-critical periods.
Solution Approach 2:
The patent performs preliminary detection by pre-identifying potential target objects and their adhesion boxes before actual shooting occurs. This preliminary action allows the system to prepare target selection data in advance, improving response accuracy while avoiding continuous real-time computation during combat.
2Measurement precision
If continuous detection of adhesion boxes is performed to improve target selection accuracy, then measurement precision is improved, but productivity decreases due to unnecessary computation
Solution Approach 1:
The system switches from continuous detection to periodic detection triggered by specific events (weapon equipping, shooting actions, target entry). This maintains accurate target selection when operations occur while eliminating wasteful computation during idle periods, thereby improving overall operation efficiency.
Solution Approach 2:
The patent extracts and isolates the detection operation to only when necessary, separating it from continuous execution. By taking out the detection function from continuous operation and placing it only at critical moments, the system maintains accuracy while improving productivity by removing unnecessary computational steps.
3Reliability
If adhesion detection is performed for all objects to ensure complete target coverage, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by differentiating detection requirements for different objects. Instead of uniformly detecting all objects, the system selectively applies adhesion box detection only to relevant target objects based on their properties and detection ranges, reducing system complexity while maintaining reliability for critical targets.
Solution Approach 2:
The detection system is segmented into multiple layers: first identifying potential target objects, then applying adhesion box detection only to those objects. This segmentation divides the complex task of detecting all objects into manageable stages, reducing overall system complexity while ensuring reliable detection of actual targets.

AI summary
A virtual prop control method includes: displaying a crosshair of a virtual shooting prop in a game scene of a virtual shooting game; detecting whether an aiming ray of the virtual shooting prop is in contact with adhesion boxes of other virtual operation objects in response to an input operation of the target virtual operation object, the aiming ray representing a direction aimed by the crosshair, the input operation including a target touch operation on a display screen that displays the game scene; and determining, from the non-target virtual operation objects corresponding to the contacted adhesion boxes, an adhesion target of the virtual shooting prop during shooting of the virtual shooting prop.
